Regional ecosystem framework

Bioregions

Bioregions of Queensland

Bioregions of Queensland

Each regional ecosystem is given a three part code. e.g.: 12.11.3

Bioregion
The first part refers to a biogeographic region that the regional ecosystem is found in. There are 13 bioregions recognised in Queensland numbered from 1-13.

 1. Northwest Highlands (NWH)

 2. Gulf Plains (GUP)

 3. Cape York Peninsula (CYP)

 4. Mitchell Grass Downs (MGD)

 5. Channel Country (CHC)

 6. Mulga Lands (MUL)

 7. Wet Tropics (WET)

 8. Central Queensland Coast (CQC)

 9. Einasleigh Uplands (EIU)

10. Desert Uplands (DEU)

11. Brigalow Belt (BRB)

12. Southeast Queensland (SEQ)

13. New England Tableland (NET)

Land zone

Land zone
The second part refers to the land zone that the regional ecosystem occurs on. The land zone is a simplified geology/substrate-landform classification for Queensland.  Find out more.

Vegetation

Vegetation
The third part is the ecosystem number and denotes different vegetation. Rainforest vegetation is classified and described using Webb's classification (Webb 1978). Non-rainforest vegetation structural classes follow a modified Specht (1970) system (Neldner, 1991). Plant names follow the current Census of Queensland Flora.

In the modified Specht (1970) system, the Herbarium describes the vegetation by the predominant strata, which is the one that is assessed as contributing the most above-ground biomass. The tallest strata is regarded as the emergent layer if it does not form the most above-ground biomass, regardless of its canopy cover, eg. E. populnea trees above a low woodland of mulga. The Herbarium measures the height and cover of each layer independently, ie. separate height and cover values for the emergent (where present) and canopy layers.

Example

Brigalow-belah shrubby open forest

In this example the unique number refers to a regional ecosystem, 11.4.3, which is found in the Brigalow Belt bioregion (region 11) that occurs on Tertiary clay plains (land zone 4) and which is usually vegetated with Acacia harpophylla and Casuarina cristata open forest (the third regional ecosystem described within the bioregion 11 land zone 4 combination).

The full description of this regional ecosystem also includes a range of associated species such as Eucalyptus pilligaensis, E. populnea, E. cambageana, E. thozetiana and E. largiflorens. In low-lying areas Melaleuca bracteata may be locally dominant. Acacia harpophylla and Casuarina cristata occur together in other situations in the Brigalow Belt, for example, on alluvial plains and on fine-grained sedimentary rocks. These latter occurrences would equate to different regional ecosystems, specifically 11.3.1 and 11.9.5.

The above example demonstrates:

  • The importance of accurately determining the land zone from geology or other available mapping such as soils and land system maps when using the regional ecosystem descriptions to verify mapping in the field, or when mapping in greater detail at a larger scale; and

  • The importance of reading the full description of a regional ecosystem in the Regional Ecosystem Description Database and associated supplementary descriptions (a list a references is provided below) which may contain useful information to assist with interpretation. For example, species variation that may occur from place to place, a particular characteristic of landform or geology and understorey species that may be diagnostic.

Further details about the regional ecosystem classification and mapping including interim numbering system for new regional ecosytems and map scale are detailed in the Methodology for survey and mapping of regional ecosystems and vegetation communities in Queensland (PDF)*.

Regional Ecosystem Framework training

The Regional Ecosystem Framework training and educational package includes a Microsoft PowerPoint presentation, divided into four sections for ease of download and a PDF document outlining the Prerequisites, Competency Standards, Assessment Strategy and Assessment Plan for undertaking Regional Ecosystem training.

The PowerPoint presentation has been prepared as a resource for certified trainers and educators undertaking Regional Ecosystem Framework training.  It should be used in conjunction with the Competency Standards for Regional Ecosystems and is mainly intended to assist with Regional Ecosystem Framework training. Trainers may alter or use its contents as appropriate to meet their own training requirements provided due acknowledgement is made.
